Betaine reduces Hcy level and paralysis rate in the absence and presence of exogenous Hcy. Hcy level was determined either in control nematodes or those treated with 1 mM Hcy. Moreover, in an additional experiment, both groups were exposed to 100 μM betaine also (a). Paralysis was determined under identical conditions as described for Hcy measurements (b). *p < 0.05, ***p < 0.001 versus the control; ^###p < 0.001 versus worms treated with Hcy
